Hi guys, I'm relatively new to the forum and would be really grateful if somebody could help me with a couple of issues... I just bought a 2001 A4 2.0 Sport privately with just under 60k on the clock. My dad, who's a mechanic, had a quick look over the engine and some basic stuff (which i know f.a about) and said that the engine was in really good nick. Unfortunately he lives in France and has gone back now so can't look at anything else in detail. There were a couple of things that are not quite so tip-top about the car and are why I, think and hope, got a good sweet price on it.

1, (Big one) The remote cl key (I only have one) doesn't work, I have to lock/unlock manually with key and this doesnt lock and unlock the back doors. I spoke to my local Audi garage and they said that they'd have to run a diagnostic check on it and that would cost over 100 notes, just to try to find out what the problem is.
2, The ESP light comes on randomly and won't go off untill I turn the off the ignition.
3, The oil pressure (i think) light is permanently on.
4, Don't have a user manual, where could I get one from..

Thanks for taking the time to read guys, know it's some heavy literature.
